S. Gorayeb et al. leg. ( MPEG 0150 ), re-examined. Diagnosis. Females of A. uiriri are similar to those of A. demiguise n. sp. and A. blakei ( Figs 13, 15 , 19, 21 ) by the medially interrupted epigynal ventral plate. They can be distinguished from those of A. demiguise n. sp. by the absence of secondary spermathecae, and from those of A. blakei by the wider copulatory ducts ( Fig. 16–18 ). Description. Male .
